commit1a8c7778bcupstream. When a VF requests promiscuous mode and it's trusted and true promiscuous mode is enabled the PF driver attempts to enable unicast and/or multicast promiscuous mode filters based on the request. This is fine, but there are a couple issues with the current code. [1] The define to configure the unicast promiscuous mode mask also includes bits to configure the multicast promiscuous mode mask, which causes multicast to be set/cleared unintentionally. [2] All 4 cases for enable/disable unicast/multicast mode are not handled in the promiscuous mode message handler, which causes unexpected results regarding the current promiscuous mode settings. To fix [1] make sure any promiscuous mask defines include the correct bits for each of the promiscuous modes. To fix [2] make sure that all 4 cases are handled since there are 2 bits (FLAG_VF_UNICAST_PROMISC and FLAG_VF_MULTICAST_PROMISC) that can be either set or cleared. Also, since either unicast and/or multicast promiscuous configuration can fail, introduce two separate error values to handle each of these cases.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
